my name is Karen and it has been about 8 years since I posted here when I lived in Washington State.
I need assistance in selecting a new pump and would appreciate any advisement you may have.
My pond was built for me by a service I would prefer not to use again because my requests and suggestions were not listened to. This service basically built the pond while I was at work and I now find that there are a few issues I am not understanding. My history was in bog filtered ponds with pumps installed via bottom drains on the floor of the pond. I know that now that it is built, I must accommodate myself to the different design and am learning that while it is different, it is known in these parts, to be effective.
The pond is 24' long by 43' wide and it is 4' deep. It is filtered by a waterfall bio filter which has a filtration box standing about 4' long and is 3' wide and 3' deep. Upon opening it found that it is loaded with large rocks and large lava rock, not the filtration material I had requested.
The pump is set into the skimmer box (about the same size as the filter box) and is HUGE. It is also very heavy. I have no idea of what it's make is except that it is shaped like a fire hydrant. It died a month or so after it's warantee expired. It sucked electricity beyond anything I have experienced and I am not willing to pay those prices again. In Washington I had two mag drive pumps on a similar sized pond and my electric bill was much more tolerable.
In consulting our local pond store, I was told that it is okay to put the pump in the skimmer box because fish poop floats to the surface. The gentleman stated that pumps will wear out much quicker when put into the bottom of the pond).
I do not have the funds to re do this pond so I am going to make necessary changes such as improving the filter material and possibly adding another filter.
What I need to know is what kind of pump would you suggest that I can put back into the skimmer box which will not kill my electric bill. I was thinking on putting two mag drives but am told that mag drives are now kind of obsolete and putting two pumps into the box with a Y connection will cause the pumps to wear out quickly (I have no clue why but I think the guy had a good albeit complex scientific explanation).
My water parameters are just fine. I started with 35 small koi and then added two really humongous ones who appear to have been a mated pair all along so my 35 number may be higher. I am happy with giving the progeny away as soon as the weather allows me to see my school.
Any ideas about a good energy efficient pump would be greatly appreciated.
Please go easy on me, I know this pond is not exactly done right.
Thanks in advance!!
